Windows 10 no longer working properly--uninstall? reinstall?

[MichaelR10]

I recently installed Windows 10 via Parallels 11. It worked entirely as expected, but now I can no longer access programs via the Windows desktop, including Internet Explorer. Can I/should I uninstall and reinstall Windows 10? If so, how? And if I do, will I have to reinstall my Windows platform programs?

Dear Michael, could you please try the steps mentioned below:
Please backup your virtual machine and try this article
Download the Registry Fix file but before you do anything else run Registry Editor and back up the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting
Right click "Windows Error Reporting" and choose "Export" and save it somewhere handy.
Then go to START> Run
then type services.msc into the run dialog box and press ENTER
Scroll down and check that the Windows Error Reporting Service is enabled. If it isn't - enable it.
Click your downloaded "Registry Fix" file - it's file name is WER_Explorer.reg and click Merge.
Reboot.
The next time Explorer crashes check for a dump file here:
